The D&D Fat Cat is a 2 into 1 stepped header design that transitions from 1 3/4 to 1 7/8” on the head pipe. This stepped design is one part of what produces the amazing torque curve that a 2 into 1 pipe will produce on a Harley Davidson motorcycle. The D&D Fat Cat will work fine with either forward controls or mid controls.
It is designed for Harley's that range from 88 CI up to the 103 CI Harley-Davidson engine but a number of very well known builders use this pipe for builds up to 120 inches. I have one on my 107" Nightrain and it put out 120hp and 115 tq on the dyno without a tune, so you know this thing can flow.
All full systems come with heat shields and baffles.
